20.500.12556/DiRROS-19642 Temperature effects explain continental scale distribution of cyanobacterial toxins nsight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains. microcystin anatoxin cylindrospermopsin temperature direct effects indirect effects spatial distribution European Multi Lake Survey true false true Angleški jezik Ni določen Neznano 2024-07-23 03:54:29 2024-07-24 12:56:42 2024-07-25 04:14:50 0000-00-00 00:00:00 2018 0 0 Nasl. z nasl. zaslona; Opis vira z dne 17. 4. 2018; str. 1-24 no. 4 Vol. 10 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2018-04-13 577 2072-6651 10.3390/toxins10040156 4673615 RAZ_Mantzouki_Evanthia_2018.pdf RAZ_Mantzouki_Evanthia_2018.pdf 1 A51CFBFBD1BEA833A5DD1637151F84B5 beb22f73239db1403664ba8ff6b87748e15dc3ae721f086e5ac7e3f107ae2a69 fe26ab51-499a-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27304 https://doi.org/10.3390/toxins10040156 0 0904979c-499b-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27306 Nacionalni inštitut za biologijo 0 0 0
